Using 93 but getting 94 and 91 Chips

[artrenee10]

the only petro we run up here in illini is 93 but I have two chips on the way, one a 91 thrasher and another burned for 94 octane (forget who's the burner) Its not that big of a deal I can get a thrasher, but my car will be laid up until then. Would it be okay to run either one of these without damaging the car? If not which one should I use?
Thanks

Id use the 91 and increase the boost slightly.

The 94 is probably going to have a good bit of timing in it. You could run it, but I'd keep the boost turned down somewhat.
